Patent number: 10756321Abstract: The present invention relates generally to electrochemical energy storage devices such as Li-ion batteries, and more particularly to a method of providing uniform ceramic coatings with controlled thicknesses for separators in such storage devices. Some embodiments of the invention utilize a layer by layer coating of nano/micro-sized particles dispersed in a solvent, which can be aqueous or non-aqueous. Other embodiments of the invention utilize a dry process such as PVD for depositing a ceramic film on a porous polyolefin separator. According to certain aspects of the invention, advantages of this approach include the ability to achieve a denser more uniform film with better controlled thickness with less waste and higher yield than current ceramic coating technology. An advantage of a ceramic coated separator is increased safety of cells.Type: GrantFiled: January 11, 2019Date of Patent: August 25, 2020Assignee: APPLIED MATERIALS, INC.Inventors: Subramanya P.

Thin film structures and devices with integrated light and heat blocking layers for laser patterning
Patent number: 9252320Abstract: Selective removal of specified layers of thin film structures and devices, such as solar cells, electrochromics, and thin film batteries, by laser direct patterning is achieved by including heat and light blocking layers in the device/structure stack immediately adjacent to the specified layers which are to be removed by laser ablation. The light blocking layer is a layer of metal that absorbs or reflects a portion of the laser energy penetrating through the dielectric/semiconductor layers and the heat blocking layer is a conductive layer with thermal diffusivity low enough to reduce heat flow into underlying metal layer(s), such that the temperature of the underlying metal layer(s) does not reach the melting temperature, Tm, or in some embodiments does not reach (Tm)/3, of the underlying metal layer(s) during laser direct patterning.Type: GrantFiled: March 30, 2015Date of Patent: February 2, 2016Assignee: Applied Materials, Inc.Inventors: Daoying Song, Chong Jiang, Byung-Sung Leo Kwak, Joseph G.
